Linear Voltage Regulator, Fast Transient Response, 500 mA with Enable NCV8177 The NCV8177 is CMOS LDO regulator featuring 500 mA output current. The input voltage is as low as 1.6 V and the output voltage can www.onsemi.com be set from 0.75 V. It provides very stable and accurate voltage with low noise and high Power Supply Rejection Ratio (PSRR) suitable for RF applications. The NCV8177 is suitable for powering RF blocks of automotive infotainment systems and other power sensitive device. 1 1 Due to low power consumption the NCV8177 offers high efficiency XDFN4 WDFNW8 and low thermal dissipation. Small 4pin XDFN4 1.0 mm x 1.0 mm or CASE 711AJ CASE 511CL WDFNW8 2 mm x 2 mm packages make the device especially suitable for space constrained applications.
